# Stock Products vs Stock Items The system uses a hierarchical structure to manage inventory efficiently: ## Stock Product This is the parent item that defines the unit of measurement and tracks costs. ## Stock Items These are defined quantities that the stock moves in and out, all related to the parent Stock Product. ## Stock Product and Stock Items Example **Stock Product**: Chips with grams as its unit * **Stock Item 1**: Chips Delivery * Quantity: 10,000 grams * **Stock Item 2**: Kids Chips * Quantity: 80 grams * **Stock Item 3**: Regular Chips * Quantity: 120 grams * **Stock Item 4**: Large Chips * Quantity of 160 grams --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
